Many pages back, so apologies if this has already been posted. Just got back to hotel after Rebels show. At fastpass line, after you scan your Mickey, the line splits in 3. We went to the left. They let everyone from the centre line in first, before doing the left line, then the right. This probably changes depending on the CM, but just a heads up.
Show was cute, but there were a lot of crying children and we had an uncomfortable experience with the family behind us, so if you have younglings it might be an idea to take something to keep them entertained while you wait. Understandable kids would be frustrated - it's in the shade inside the theatre, but I wouldn't describe it as "cool". Take a drink in with you, if possible - you can get ice water for free from the counter service Windows opposite.
Show was lovely. Ezra and Sabine do a quick skit, there's a recap of season 1, JAT interviews Tiya about Rebels and shows clips of her other work, then there's a preview of a fight scene from season 2, introduced by Chopper. Scene lasts maybe a minute and a half. Really enjoyed it, but younger kids may not be interested in the interview section.
